Abstract

Method of calibrating a first clock signal using a second clock signal and calibration periods may include generating incremented counter values at a counter responsive to edges of the second clock signal. An initial incremented counter value may be stored at an initial edge of the first clock signal for the respective calibration period, a final incremented counter value may be stored at a final edge of the clock signal. The calibration periods may be overlapping with different initial and final edges of the first clock signal. For the calibration periods, a number of edges of the second clock signal occurring during the respective calibration period may be determined. A relationship between the clock signals may be determined using a sum of a number of edges of the second clock signal and using a sum of a number of clock signal cycles occurring during the calibration periods.
